WHM coo-M 4? a? zgmg pinion -ll and the .uutteeth the stuh-shz'ift3'75'1nay be turned by the inoend to the rod retains the said rodnormally projected and the bolt in locking engagement with one of thenotches of the disk 2%, while the other end of the springs is providedwith a hook 52 adapted to removably engage the post 53 of the vehicleframe. a

A. stub shaft positioned longitudinal and substantially central of thevehicle frame has one end journaled in a thrust bearing 5i of the sill16 and said stub shaft has adjustably geared connections with the enginedriving shaft 34 by means of the speed and direction changing gearingwithin the casing 12, while a gear 35 secured to the said stub shaft 33is in constant mesh vith a similar gear 36 which is freely journaledupon the vehicle power shaft 13. A clutch collar 37 is slidably mountedupon the power shaft 13 and being made revolublo tli.ei' .-.ritli bymeans of the spline 38 so that the inter-engagement of the clutchfingers :52) oil the member 37 withthe clutch lingers h) of the gear 36will lock the gear with the shaft 13. A pinion ll is slidably splincd tothe stub shaft 33 and is adapted to mesa with the teeth of the beveledflange 21 of the jack screw operating not 20., A shiftable bracket 4.2of angular form is slidahly mounted upon the stub shaft and has one fork4.3 freely connected Withthe pinion ll and another fork i l freelyconnecting the clutch member 37 While a clutch lever at is pivoted tothe said bracket for moving the same longitudinally of the vehicle, Fromthis arrangement it will be seen j that when the pinion. 41 and clutchinei'nne li' are out of contact with'their cooperating members as shownin Fig. 2, the on construction will be inoperative so that a driving ofthe stub shaft by the motor 11 will only revolve the journaled gear 36and the spiined pinion l-l without influencingeither the nut 20 or thepower shaft 13. lipon moving the J bracket will be rewardly influencedthus u'ioving'tho pinion all mesh with the nut teeth 2i. while thc"liitch member 37 will be further removed from the power shai't gear35 and the turning of the motor will turn the stub shaft in Whicheverdirection desired under the control of the change gears within thecasing 12. The is provided With 2: 'er end of the jack 5: a circulardisk or base 45 having projecting t'ccth' lli upon the bottom thereofand adapted to engage the roaddied or other surface upon which thevehicleis positioned lVhen the sort base normally positioned with ractedand as illustrated in dotted lines in l igl 1., ameshing. of the 21being elfcctod,

tor in the le. red direction for turning the nut 20 to downwardly sh ftthe ack-screw 4i forwardly, the

and its base until the latter engages the ground as illustrated in Fig.,1 and whereupon a farther turning of the nut 20 will elevate thevehicle upon the said screw. A reversing in direction of the stub shaft33 through the agency of the change direction gears will result inturning the nut 20 in the opposite direction and thus lowering theautomobile to the roadway and thereafter a retracting of the screw toits original norinal position. During the use of the jackscrew as abovedescribed, the lock bolt 26 is held engaged with one of the teeth of thedisk 24 by means of the spring 32 and when it is desired to turn thevehicle around upon the said screw as a pivot at any time that thevehicle is elevated thereon, the handle 31 may be pushed inwardly whichreleases the bolt from the lock disk and whereupon the vehicle may bemanually swung around after the manner of a turn table and thus readilypositioned in any desired direction. The casing 47-7 is mounted upon thetop of the sill 15 and has a central opening 48 for receiving the upperend of the jack-screw While the lever i27'ias well'as the bolt and thepivoted end of the lever 30 are housed 'in a chamber ll) thereof, whilethe casing is secured to the said sill by means of holdfast devicesprojecting within sockets 50 of the sill. i

While the fornrof the invention herein shown and described is what isbelieved to be the preferred cmbi'idimcnt thereof, it is nevertheless tobe understood that minor changes may be made without departing from thespirit and scope of the invention as claimed.

What I claim as new is:

l. A device of the class described comprisi of; a vehicle having spacedtransverse sills positioned. one above the other and provided withalinin-g openings thercthrough, a jack screw freely slid-able within thesaid openr ings, an operating nut between the said sills and threadedupon the said screw, and provided with a ti'iolhcd flange, aground-engaging base plate ug'ion'the lower end of the sai screw, amotor, clutching means between the said motor and toothed flange anddirection changing means for the said clutcl'i'ing means.

2. A .(lovicc ol? the class described comprising a veh le having spacedtransverse sills positioned one above the other and provided withaliningopenings therethrough, a jack screw freely slidable within thesaid openings, an operating nut between the said sills and threaded uponthe said screw, andv provided with a toothed flange, a ground-engagingbase plate upon the lower end of the said screw, a motor, a stub shaft,direction, changing means between said motor and shaft,'a slidablepinion splined to the said shaft adapted to mesh with the said toothedflange and shifting means for the said pinion.

A device of the class described comprising a vehicle having spacedtransverse sills positioned one above the other and provided withalining openings therethrough, a jack screw freely slidable within thesaid openings, an operating nut between the Said sills and threaded uponthe said screw, and provided with a toothed flange, a ground-em gagingbase plate upon the lower end of the said screw, a motor, a stub shaft,direction changing means between said motor and shaft, a slidable pinionsplined to the said shaft adapted to mesh with the said toothed flange,shit'table means for the said pinion, the said screw provided withlongitudinal slots therein, a disk having inwardly projecting lugsslidably engaging within the said slots and also having peripheralteeth, a lock bolt slidably mounted upon one of said sills and normallyengaging the said disk, and releasing means fertile said bolt.

at. A device of the class described comprising a vehicle having spacedtransverse s1lls positioned one above the other and providedWithaliningopenings therethrough, a jack screw freely slidable Withinthe said openings, an operating nut between the said sills and threadedupon-the said screw, and provided with a toothed flange, aground-engaging base plate upon the lower end'of the said screw/amotor, a stubshaft, direction changing means between the said. motor and stub shaft,a slidable pinion splined t0 thesaid stub shaft, and adapted to meshwith the said toothed flange, a gear secured to the said stub shaft, apower shaft for the vehicle, a gear freely journaled upon said poweshaftin constant mesh, with the said stub shaft gear, a slidable clutchmember splined upon said power shaft and adapted for interlocking withthe said power shaft gear, and simdltaneous. operating means for thesaid pinion and clutch member.

In testimony whereof I aiiix my signature in presence of two witnesses.
